Tyson Fury's tip as the looming threat in the heavyweight division is Joe Joyce, says promoter Frank Warren.
Undefeated Joyce is the mandatory challenger for the WBO belt that Oleksandr Usyk took from Anthony Joshua in a masterful points victory at Tottenham Hotspur Stadium last month.
But Usyk and Joshua's rematch for the IBF, WBA and WBO belts, expected in spring 2022, means Joyce will be made to wait for his guaranteed opportunity at a world title.
"I was talking to Tyson about him," Warren told Sky Sports.
"Tyson said that he's the best one out there. That's what Tyson's opinion was.
"Can he go all the way? Yes he can.
"He's got a good ticker, a big heart. He's strong, he walks forwards, he is the 'Juggernaut'.
"Whoever he's in there with, you know they will have a problem getting rid of him.
"He's a tough guy. He can fight a bit. He can punch."
Joyce brutally stopped Daniel Dubois in a battle of then-unbeaten British contenders last year.
He has since stopped Carlos Takam.
Joyce was previously in talks to fight Usyk at the same time as Fury and Joshua were negotiating their doomed undisputed title fight.
Usyk defeated Joyce on points in an amateur fight in 2013, but Warren insists a future collision under a professional rule-set would be different.
"Him and Usyk would be a great fight," Warren said. "He could hurt Usyk, he's a big man.
"Could he beat Usyk? Yes. He fancies it and I fancy it.
"He isn't going to back off Usyk. He'd let his shots go.
"It won't be the little man out-jabbing the big man - that will not be happening."
Usyk's rematch with Joshua next year means Joyce is likely to re-enter the ring and risk his status as a future challenger.
"We're waiting to hear back from the WBO because some of the governing bodies will be making decisions about their mandatory challengers for Usyk, and when they are going to be," Warren said.
"What we don't want to do is to compromise his position.
"Hopefully in the next couple of weeks we can make a decision."
Olympic gold medallist?
Joyce lost the 2016 Olympic super-heavyweight final to Tony Yoka but that bout is one of 11 cited in an independent investigation that found officials manipulated results.
Joyce took home silver but, five years on, his fight is being investigated.
"It's outrageous," Warren said.
"The sport may be banned from the next Olympics as a result of this.
"It's wrong. These guys shouldn't be waiting five or six years until they get their medals."
